Lucas 5th Wheel Slider Lube is a clean, easy to use solution for the problem of dry 5th wheels and slider rails. It is waterproof which means it will not wash off slider rails on wet roads. Also, it is easy to use and is an inexpensive alternative to grease for 5th wheels and sliders. Above all, it has a film strength stronger than regular grease. Likewise, since it is not a grease it will not leave soap behind after the lubricant is exhausted. This will help minimize maintenance issues in the lock mechanisms.
